macOS 27 removed the master switch for Apple Intelligence, leaving users to toggle off a dozen scattered settings one by one — and even then, the AI models stay on the disk. Independent developer Om Lahore released RemoveMacAI on GitHub last weekend: a free, MIT-licensed command-line tool that disables the features and deletes the models in one command, reclaiming about 12GB, the developer says. But the press consensus is unanimous: think twice first.
Ars Technica reported on Oct. 5 that macOS 27 (codenamed Golden Gate) offers no global Apple Intelligence toggle; users must hunt down roughly a dozen settings, some buried under Screen Time — and the base models remain on disk, about 12GB worth, in the developer's own words on Reddit (quoted by WebProNews). "I wrote RemoveMacAI to handle it all in one command."
RemoveMacAI installs via a one-line curl command or Homebrew. Running it shows the current status, asks for confirmation, then opens System Settings — where the user must manually approve a configuration profile, a step macOS mandates and the tool cannot skip (Cult of Mac). The profile applies Apple's own restriction keys to switch off the features and deletes downloaded models through Apple's asset service — without disabling SIP or modifying anything under /System; deleted models' download URLs are redirected to a closed local port so they can't flow back, and the profile survives macOS upgrades (WebProNews, Cult of Mac). Companion commands include `removemacai status` to list each model's footprint, a dry-run preview mode, and one-click rollback via `removemacai revert` (9to5Mac, NewsyNext).
The developer's figure is about 12GB, echoed across Ars Technica, 9to5Mac, Cult of Mac and MacRumors. Apple's official line: up to 7GB on macOS 26, up to 14GB on newer Macs running macOS 27 (9to5Mac, citing Apple's support pages). Real-world reports run higher: MacRumors on Oct. 6 cited a user freeing more than 20GB; MacDailyNews and Cult of Mac noted 30GB-plus readings in System Settings; AnalyticsInsight logged 35GB on a MacBook Air. Side effects: apps using the Foundation Models framework, the Shortcuts "use model" action and Visual Intelligence stop working; Dictation is unaffected (9to5Mac).
The "think twice" framing comes from 9to5Mac: this is an unofficial third-party tool making system-level changes, and nobody knows whether Apple will ask GitHub to take it down or break its underlying mechanisms in a future macOS. Cult of Mac flags a sharper risk: the developer himself warns that some restriction keys the tool relies on were deprecated by Apple in macOS 26.4 — they still work in 27.0.1, but a future update could kill them at any time. WebProNews advises reading the code first, rehearsing with dry-run, backing up, and considering Apple's built-in toggles.
The tool earned 1,700 GitHub stars in its first week, sparked debate on Reddit and Hacker News, and was warmly embraced by "AI skeptics" (WebProNews, MacRumors, MacTrast). Apple declined to comment (WebProNews). For Mac users short on storage, RemoveMacAI offers an unofficial way out — at the price of handing system-level trust to a stranger's repository, and accepting it could break with some future software update.
